Phone settings and watchface settings

Hi!

How have people implemented both watch and phone settings storage.
I mean that I implemented watch settings where I can set and get values directly on the watch.
I also have the possibility todo more specific settings with the phone. How to choose which one to choose, because phonesettings uses

App.getApp().getProperty(key); and App.getApp().setProperty(key, val);

and the watch uses

Storage.getValue(key) and Storage.setValue(key, val);

So if I first save e.g with the watch settings it works, but when I save with the phone, how to retrieve the most recent value from the Storage or the App.getApp()?
Hope you understand what I mean :)
